Droid X wifi connection Prolems! HELP!?

[Revolution Time!!]

up until two days ago my wifi connection was doing fine and then all of a sudden it stopped working. it shows connection and tells me "connection Detected" but when i try to go on the browser or access an app that requires internet it says "no connection" or network error. i tried disconnecting the router and turning off my phone and i think that helped a little bit because i can go on the browser and watch videos on Youtube but i cant log in on facebook or access the play store because it tells me "no connection". i cant find the problem and i really don't want to factory data reset my phone. help please!
